Recent experiments with liquid lithium in magnetically confined plasmas have demonstrated improved plasma performance. These results have led researchers working on the National Spherical Torus Experiment to consider using a porous molybdenum foam and liquid lithium composite as a future liquid lithium divertor. In order to better understand the properties of this composite material, a small experimental apparatus was constructed at the University of Illinois to test lithium wetting uptake into the porous material. We report here results of the wetting behavior of a porous molybdenum foam with liquid lithium. Based on these observations, a simple model was used to estimate the thermal properties of the lithium infused porous material. Finally, the results of water-bath cleaning tests of the porous metal after lithium exposure are shown.
